My oil cool had a hole in, the oil got into the coolants mixed and made a gooey mixture much like pancake batter but not water soluble. Please, what will dissolve that mess? I am have tried a quart of radiator flush. Not much help, i keep flushing but it just does not come clean.

Dawn dish soap. I know it sounds strange but Dawn cuts grease out of your way like the commercial says.

Yup, beats just about any of the "radiator flush" stuff sold in parts stores. Run the engine until it is warm, pour in about a half cup of Dawn. Then run it until it is up to full temperature. Let it cool down and then heat cycle it again. Drain out the mess. Do it again and then flush it with clear water. Should come out clear now. Refill with 50/50 mix and enjoy.
